tain new and usefullmprovements' inLoom Shuttle-Binders; and I do declare the following to be a full, clear, and 'exact description of the invention,- such as will enable others skilled in the art to which it appertains to make and use the same. I I

My invention relates to improvementsin loom shuttle binders, and 'has for itsl object to provide means whereby shuttles contained in the shifting shuttle boxes will be reliably held thereinl against accidental movement until impelled outwardly by the picker-stick.

It has been found that during the course of operation of the loom, the usual springs on the shuttle binders require constant attention to maintain them at a correct tension so as to prevent any slipping ofthe shuttles. If the spring is too loose, the shuttle will frequently slip out, and if it is adjusted too tightly, the binder is pressed too close to the box to allow the shuttle to go completely into its cell; in either case a smash generally occurs, often doing considerable damage to the operating parts of the loom.

My invention is designed toovercome this objectionable feature of'loom operation by providing means on the binders to be used in conjunction-with the usual binder springs for retaining the shuttles. These binder springs are adjusted rather loosely so as to allow the shuttles to easily slide completely into their respective cells into the shifting shuttle boxes, where they can then be acted upon by my improvement to prevent them from slipping out until struck by the pickerstick.

The accompanying drawing fully illustrates my invention, wherein:

Figure 1 represents a rear side view of a` shifting shuttle box and part of the lay end in which the said shuttle boxes rise and fall in the usual manner;` Figs. l2 and 3 are longitudinal sectional views taken on the lines 2-2 and 3)#3 ofFig. 1; and Fig. 4 is a detail transverse section through the binder, taken on the line 4-4 of Fig. 2.

In the drawing, I have shown a sufficient portion of the loom for illustrating my invention, L designating a portion of the lay shaped to receive the usual shifting shuttle box frame on which'the usual shuttle cells C are mounted, a binder 1 of the usual construction being positioned for cooperation with each of the cells. A shuttle box rod R is used foractuating the shuttle box frame. These binders 1 are of the usual construc- .tion for use on looms of the type illustrated,

each oflwhich comprises an arm 2 provided at one end with an ear 3 having an opening therethrough adapted to receive a pin 4f for pivotally connecting said binder to the shuttle box in the lusual manner. A spring 5 usually designated as the lbinder spring, has one endV adjustably secured to the shuttle box'frame and has its opposite end disposed against the outer face of the binder at 6, and is used to press said binder toward the box so as to retain the shuttle therein before being acted upon by the picker stick. As hereinbefore stated, this binder spring requires frequent adjustment in order to obtain the correcttension of the binder to prevent slipping of theshuttle. Y v The foregoing described parts are common to all looms and form no part of my invention, they having been merely described for the purpose of clearly setting forth my improvement. As all the binders are similarly equipped with my improvement, but onel will be described.

A circular opening 7 is formed through the binder substantially in its center, but slightly nearer to the pivoted end than the other, .and is adapted to receive therethrough a detent 8 which is provided with a cam faced or hemispherical active end 9 for coaction with a seat 10 formed in one face of. the shuttle. This seat 10 is of a shape to snugly receive the active end 9 of the detent andv has its edges slightly round- Fig. 1 of the drawing. A pair of ribs 14 are formed on the outer face of the binder, one of said ribs being disposed on each side of the opening 7, extend longitudinally of the length of the binder and are adapted to receive therebetween the spring 12.

When the. shuttle is knocked across the` loom through its raceway and into its compartment in the shifting shuttle box, 1t will force the binder outwardly against the ten- Because of its formation, the edge of thev seat 1G will force the detent outwardly when the shuttle is struck by the picker-stick and allow the same to be projected out of the box and through its raceway to its box on the other side of the loom whore the operation will be repeated.

From the foregoing' description, taken in connection with the accompanying drawing, it is obvious that I have provided a very simple device for carrying out the object of my invention, and one which can be readily applied to binders already in use.

I claim:

l. In a loom shuttle binder having an opening therethrough, a detent disposed in said opening and having a hemispherical active end projecting beyond the inner face of said binder, the opposite end of said detent being l'lat, longitudinally extending parallel ribs disposed on the opposite sides of said opening, and a flat leaf spring secured by one end to the flat face of the detent and disposed between said parallel ribs, its opposite end being secured to the binder adjacent its free end.

2. In combination with. a shifting shuttle box, of a shuttle having a hemispherical scat in one side, the edges of said scat being rounded, a shuttle binder having a circular opening therethrough, a cylindrical detent slidable through said opening and having a hemispherical active end projecting beyond the inner face of said binder, the opposite end of the detent being flat, a flat leaf spring secured by one end to the Vtlat tace of the detcnt, its opposite end being secured to the binder adjacent its free end, longitudinally extending' parallel ribs disposed on the opposite sides of said opening and receiving said spring therebetween, said detent moving into and out of said seat when the shuttle is actuated by the picker stick, and a spring for holding said binder in contact with said shuttle.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
